Fibril-associated Collagen01:11

Fibril-associated Collagen

3.8K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Type IV Collagen of Basal Lamina01:05

Type IV Collagen of Basal Lamina

3.4K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen  forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
A type IV collagen molecule has six alpha chains which can...

Summary

Asiaticoside and madecassoside, compounds from Centella asiatica, significantly boost type I collagen production in skin cells. Madecassoside also enhances type III collagen secretion, vital for skin health and wound healing.

Area of Science:

  • Dermatology
  • Biochemistry
  • Pharmacology

Background:

  • Type I and III collagens are crucial for skin structure and function.
  • Decreased type I collagen levels are associated with skin aging.
  • Collagen I is vital for effective wound healing.

Purpose of the Study:

  • To investigate the effects of asiaticoside and madecassoside on collagen secretion in human dermal fibroblasts.
  • To determine the impact of these compounds on type I and type III collagen levels.

Main Methods:

  • Human dermal fibroblast cultures were established from a skin sample.
  • Fibroblasts were treated with asiaticoside and madecassoside in serum-free medium.
  • Enzyme-linked immunosorbent assay (ELISA) was used to quantify type I and III collagen secretion.

Main Results:

  • Both asiaticoside and madecassoside increased type I collagen secretion by 25-30%.
  • Madecassoside significantly stimulated type III collagen secretion.
  • Kinetics of secretion were determined at 48 hours for collagen I and 72 hours for collagen III.

Conclusions:

  • Asiaticoside and madecassoside stimulate collagen synthesis in dermal fibroblasts.
  • These compounds hold potential for therapeutic applications in skin aging and wound healing.
  • Madecassoside demonstrates a notable effect on both major collagen types in the skin.
